Abstract: A resolver circuit including a signal generation circuit, a bridge tied load amplifier, a resolver, and a resolver processing circuit is provided. The signal generation circuit is configured to generate an excitation signal for driving the resolver. The bridge tied load amplifier, having an input in electrical communication with the signal generation circuit, is configured to amplify the excitation signal. The resolver has an excitation winding and an output winding, with the excitation winding being in electrical communication with the bridge tied load amplifier. The resolver processing circuit is electrical communication with the output winding of the resolver to determine the angle of rotor of the resolver.

Abstract: An apparatus and method is provided for an improved brake shift interlock system which reduces solenoid noise created by vehicle vibrations and solenoid activation. The brake shift interlock system includes a park position switch, a brake sensor, and a control circuit. The method includes the sensing of the park position switch and the brake sensor and generating a pulse width modulated control signal having a varying duty cycle for driving the solenoid when predetermined conditions of the park position switch and brake sensor are sensed.

Abstract: An apparatus and method is provided for an improved brake shift interlock system which eliminates the need of a redundant park position switch. The number of components is minimized due to an incorporation of a latch within the brake shift interlock system. The apparatus also eliminates the need of a cam and wiring harness, as well as manual labor traditionally required to install these components.

Abstract: An apparatus for a continuously variable semi-active suspension system using centrally located yaw rate and accelerometer sensors. The yaw rate sensors measure both pitch and roll. The vertical accelerometers measure bounce. Locating the sensors near the center not only centralizes the sensors, reducing wiring, but also reduces noise and simplifies calculations by not having to project measurements to the center of gravity.
